Calculate the concentration of F- present in the Mg2+/Y3+ solution when the first (initial) cation begins to precipitate, and the concentration of F- present in this solution when the second (final) cation begins to precipitate. Write down which cation precipitates first and which precipitates second (last). Choose the correct statement from below based on your work. a) The molarity of F- which begins to precipitate the initial cation is 4.06e-12 M. b) The molarity of F- which begins to precipitate the initial cation is 4.43e-25 M. c) The last metal cation to precipitate is Y3+ . d) The molarity of F- which begins to precipitate the final cation is 1.00e-06 M. e) The molarity of F- which begins to precipitate the final cation is 2.56e-05 M.
